摘要

Gas abnormal zone in a law gaseous mine is a potential hidden peril of gas accident. Study of geological features, seam thickness and structure, coal block texture, hydrogeological conditions in gas abnormal zone and so on indicates that gas abnormal zone is closely related to geological abnormal zone. This paper deals with gas abnormal zone in the last five blocks in the Panxi Mine. Study results indicate that gas burst occurs mostly in coal seam in the lower wall of fault F7-1.
